sysbench 多线程异步io模拟mysql测试的脚本

用于测试的脚本：

for size in 100
do

cd /mnt/stec
sysbench --test=fileio --file-num=1 --file-total-size=${size}G prepare
sync
echo 3 > /proc/sys/vm/drop_caches

for numthreads in 4
do
sysbench --test=fileio --file-total-size=${size}G --file-test-mode=rndwr --max-time=3600 --max-requests=0 --num-threads=$numthreads --rand-init=on --file-num=1 --file-extra-flags=direct --file-fsync-freq=0 --file-io-mode=sync --file-block-size=16384 --report-interval=10 run | tee -a run$size.thr$numthreads.txt
done
done
